I'm currently on week 3 of a 10 week cycle of Sustanon 500mgs. and Deca 400mgs. And I've decided to do a bit of an extended cycle. I'm thinking about going 20 weeks altogether. My question is this: Is it true that a certain AAS will lose some of its effectiveness over a longer period of time? If so, is 20 weeks long enough to cause the effects to diminish? I don't know how true the whole receptor saturation thing is. Also, my alternative to the above cycle is Fina 75mgs. a day and EQ 400mgs. per week. Which do you think is a better idea? Running the current compounds for 20 weeks? Or running it for the original 10 and than switching up to the Fina cycle for the other 10?
